Hear This: Kendrick Lamar - The Heart Part 4

Kendrick Lamar is back to save us all with new track 'The Heart Part 4'.
The song dropped last night following a since-deleted Instagram post hinting at new music, which many speculated pointed to his highly anticipated follow up to 2015's acclaimed To Pimp a Butterfly.
It comes as his first solo release since last year's untitled unmastered. and serves as the fourth instalment of his 'Heart' tracks since 2009.
Switching between beats and amping the intensity as the five-minute track goes on, Lamar takes swipes at "chump" Donald Trump and the latter's involvement with Russia, as well as an unnamed rapper which fans have since theorised to be Big Sean.
The song then ends with the line: "Y'all got 'til April the 7th to get your shit together." Could this be the potential release date for his fourth album?
Listen to the track below.
